In regards to the weight... the 6d weighs almost exactly the same as the d7100. Does that camera work for you to carry around all day? The 6d is good for me, but the weight seems to be more about lenses than it is about the body in my usage. I like that the 6d is lighter than the 5d mkIII, but the 24-105 that I have on it is what makes it heavy, not really the body itself (and most consider that lens pretty light and small actually...)
